Nothing is built-in. Packages communicate with each other like
everything else in OI, through common names of registered
components. This is normally seen in two ways:
- SPOPS object name-to-class mappings
1.x: my $object_class = $R->object_name
2.x: my $object_class = CTX->lookup_object( 'object_name' )
- Action handler name-to-class mappings
1.x: my $action_info_hash =
$R->lookup_action( 'action_name',
{ return => 'info } );
1.x: my ( $action_class, $method ) =
$R->lookup_action( 'action_name' );
2.x: my $action_obj = CTX->lookup_action( 'action_name' );
my $action_name = CTX->lookup_action_name( 'url' );
my $action_info_hash =
CTX->lookup_action_info( 'action_name' );
In 1.x you can also use $R to pass around information as
necessary. It's a little hackish (that is, not built-in) but it's
fairly easy to do, and all your packages need to agree on is what
name to use ('tmp_box_links' in the example below). For instance,
in your box handler you could have:
sub handler {
my ( $class, $params ) = @_;
# These are the links used in the box call
my $my_links = $params->{links} || [];
# These are the links added by other people
my $other_links = $R->{tmp_box_links} || [];
my @all_links = ( @{ $my_links }, @{ $other_links } );
return $R->template->handler(
{}, { links => \@all_links }, { name => 'mypkg::tmpl' } );
}
Since OI 2.x represents all actions, including boxes, as objects
you can store state in them from anywhere you wish. Much more
flexible.
Hope this helps,
